For millennia, humans have used more and more land for agriculture, taking over wild habitats.

But, we are at a unique point in history: agricultural land use has peaked.

My latest article:
ourworldindata.org/peak-agricultu…
While agricultural land use has fallen, the amount of food we produce has continued to increase.

This is a decoupling we saw much earlier in today's rich countries, but is now true at the global level.
It's important to understand what's driving this change.

Global pasture land has peaked. Global cropland has not.

How can this be, when we produce more meat than ever?

I explain in the article 👇

2/
It should go without saying that land use has not peaked everywhere.

And croplands are still increasing in some regions.

That is why continuing to increase crop yields across the world is so critical if we're to prevent this trend from reversing.

For millennia we have taken more & more land from other species to produce food.

It doesn't have to be this way. We are in a unique position where we can be the first generation that gives this land back, while producing *more* food at the same time.

Humans have driven many of the world's mammals to extinction. This threat has been persistent throughout our history.

But, recent conservation efforts show that it doesn't have to be this way.

Mammals are making a comeback across Europe.

My new article: ourworldindata.org/europe-mammal-…
As I covered in a recent @OurWorldInData article, the largest mammals have always been at the greatest risk of extinction.

This is still the case across the world today.

1/

ourworldindata.org/large-mammals-…
@OurWorldInData But we are now in a very unique position. We can be the ones to turn the tide – bringing wildlife back, rather than pushing it to extinction.

This is happening across Europe. Conservation efforts over the past 50 years have been extremely successful.

What is the world's most pressing problem?

Many answers. Increasing agricultural productivity across Sub-Saharan Africa makes it into my top five.

It's vital to reduce hunger, poverty and biodiversity loss.

My latest post: ourworldindata.org/africa-yields-…
Labor productivity in agriculture across Sub-Saharan Africa (and most countries in the region – obviously there is significant heterogeneity) is very low.

Most work in farming and earn very little.

To reduce poverty, labor productivity has to increase

1/
Crop yields have increased in many countries in recent decades, but are still very low.

Yields lag behind other regions, and are a small % of attainable yields.

To preserve natural habitat, yields need to increase.

Many people could face hunger this year as a result of rising food prices, and reduced exports from Ukraine & Russia.

What could we do, and can this change quickly enough?

Thread with some numbers for perspective 👇
To be clear: any food shortages would not be because the world does not grow enough to feed everyone.

The world uses about 214 million tonnes of maize for industrial uses (mostly biofuels).

US biofuels alone is several multiples higher than Ukraine + Russian exports 👇
For wheat, there is less potential for displacement from biofuels. Especially if the world was to limit exports from Russia, which are large.

Important for food security to not limit Russian food exports if we cannot manage supply from elsewhere.

Next week the @IEA will hold its 2022 ministerial meeting.

Countries have the option to make global energy data free & open for everyone. It's even more important now.

@MaxCRoser & I explain why, with a new section on energy security👇

ourworldindata.org/iea-open-data Image
@IEA @MaxCRoser Understanding energy dependency, security & trade across the world has been critical in recent weeks.

You'd think that this would be easy, but it's not.

Researchers have been scrambling to try to find very basic but critical data on energy trade across the world.

1/
@IEA @MaxCRoser The @IEA has this data but nearly all of it is locked behind paywalls, costing hundreds of dollars each.

Even if you purchase a license, you then cannot share the data with others.

Food security across many countries – particularly across the Middle East and Africa – could be a big concern in the coming months.

A short thread on how the war in Ukraine could affect food supplies.

🧵👇
Both Russia and Ukraine are among the world's largest wheat exporters.

Russia is the largest exporter. Ukraine is 5th.

Combined, they account for more than one-quarter (around 27%) of global exports.

1/

ourworldindata.org/explorers/glob…
Both countries are also among the largest exporters of maize (corn).

Ukraine is 4th. Russia 6th.

Combined I estimate that they account for around 16% of global exports.
